Were you using the newer version?  If not, that's bad news....well at least for me. 
What did you use to monitor bandwidth?  My TuxMath also ran fullscreen, is yours
windowed?  If so maybe I'll run windowed and test again.  

As far as running slow, I guess regardless of CPU/RAM/Network usage, if it runs too slow
to use it doesn't do much good anyhow.  We have 7-12 grades here, so I don't really need
TuxMath.  But it would be nice for elementary schools.
